Description
EQUIPMENT FOR REGISTRATION AND TRANSMISSION OF THE MEASURED VALUES OF PHYSICAL AMOUNTS, AND MEASURING SENSOR FOR THIS
EQUIPMENT
The invention relates to a device for recording and transmitting the measured values of physical quantities, such as those comprising:
at least one autonomous measurement sensor, driven by an electric cell, comprising a transmitter capable of transmitting at various times at least one value measured by the sensor,
- and a receiver to collect the values transmitted by the transmitter.
The invention relates more particularly, but not exclusively, to such equipment for the remote registration of meters of fluid, mainly meters of water, as explained in patent application FR No. 2,904,668, filed on 4 August 2006 under No. 06 07161 and published on February 8, 2008.
The invention applies in particular to measurement sensors that communicate with a receiver, forming a central location, by means of an appropriate transmission means, in particular by means of a radiofrequency or wiring device.
In order to conserve in a work order
This equipment for recording and transmitting the measured values, it is appropriate to ensure the proper maintenance of the measurement sensor, essentially replacing the sensor before its power cell fails.
Currently, the cells used for this type of application, mainly lithium cells, can have lifetimes of 15 years and more for powering electronic circuits, but this period varies greatly, mainly depending on the temperatures sustained during life of the sensor. To reduce the risks of the measuring sensor failing due to draining the cell, cell manufacturers usually tend to underestimate the life and oversize the cells for a given application. Operators generally tend to prematurely replace the sensors with their cells, as a measure of prevention.
The result of this are relatively high operating costs.
The object of the invention is mainly the improvement of the operation and maintenance conditions of a device for recording and transmitting the measured values of physical quantities.
According to the invention, a recording and transmission equipment of the type defined above is characterized in that:
- the sensor comprises a means for measuring the temperature in the vicinity of the cell,
- a link is provided to supply the transmitter with the values of the temperature that were measured, transmitter that is designed to transmit, in addition to the values of at least one physical quantity, these measured values of the temperature, at determined intervals,
- and the receiver is designed to store the measured values of the temperature, estimate the life of the cell taking into account these measured values, and determine a replacement date for this cell.
Advantageously, the receiver is designed to establish a temperature profile of the cell as a function of time, and comprises a means to compare with the typical profiles the temperature profile that has been recorded, in order to estimate the probable life of the cell .
Preferably, the receiver comprises an electronic circuit capable of initiating an alarm when the measured values of the temperature exceed a certain threshold.
In particular, if the measurement sensor is set for a water meter, the receiver comprises a low temperature threshold to activate the alarm below 0 ° C, in order to warn of the risk of
freezing
The receiver may also comprise a high temperature threshold to activate the alarm, mainly of the order of 60 ° C, corresponding to the maximum temperature that the cell or the sensor itself can support, or an element of the latter.
A device as defined above is advantageously installed in a network for the delivery of fluid, in particular water, with sensors installed in the fluid meters, and the transmitters of the sensors make it possible to ensure a remote recording of consumption.
The invention also relates to an autonomous measurement sensor, driven by an electric cell, for a device for recording and transmitting the measured values of physical quantities, comprising a transmitter capable of transmitting at different times at least one measured value supplied by the sensor, and characterized in that it comprises a means for measuring the temperature in the vicinity of the cell, and a link that is provided to supply the transmitter with the measured values of the temperature, transmitter that is designed to transmit, in addition to the values of at least one physical quantity, these measured values of the temperature, at determined intervals.
Apart from the configurations mentioned above,
The invention consists of a number of other provisions which will be considered more explicitly below, with reference to an example embodiment which is described with reference to the accompanying Figure, but which is in no way limiting. In this Figure:
Figure 1 is a simplified diagram of a device for recording and transmitting the measured values of physical quantities, in the case of a water meter.
Figure 2 is a simplified diagram of the electronic circuit with the means for measuring the temperature and with the transmitter, and
Figure 3 is a diagram illustrating the possible temperature profiles over time.
With reference to Figure 1 in the drawings, it is possible to see, represented schematically, a device or an installation for recording and transmitting the measured values of physical quantities. This equipment comprises at least one autonomous measurement sensor (1), driven by an electric cell (2), comprising a transmitter (3) with an antenna (4), capable of transmitting by radiofrequency at various times at least one measured value by the sensor (1). The equipment also comprises a receiver (5) to collect the values transmitted by the transmitter (3). As a variant, the transmitter (3) could be connected to the receiver (5) through a
wired device, and may not include an antenna.
The measurement sensor (1) can be of the type described in the aforementioned patent application, FR 2 904 688, and be installed in a water meter (D). The measurement sensor (1) comprises a transducer sensitive to the rotation of a metallic element and capable of creating the digital information corresponding to that rotation. The sensor with its transducer is placed against the water meter (D) and the digital information corresponding to the consumption is sent to a microprocessor (6), programmed to process this information and communicate it to the transmitter (3).
In the diagram of Figure 1, only the sensor (1) has been shown. Of course, several sensors such as (1), corresponding to several meters (D), can be associated with one and the same receiver (5) that constitutes a central site.
In general, the invention relates to sensors in the broad sense, and more precisely to the meters of liquids or gases sensitive to ambient temperature (water meters, for example), either because the liquid itself is sensitive to temperature (for example to freezing in the case of water), or because 1 measuring device is sensitive to it due to the technologies used (cold temperature for liquid crystals or
the cells, high temperature also for the cells or for certain plastics).
The electronic circuit comprising the microprocessor (6), which is provided in a communication sensor, makes it possible to read and periodically transmit the physical quantity or quantities in question, mainly the volume of the fluid delivered in the case of a measurement of fluid.
An important advantage of these measurement sensors is that they make it possible to make remote consumption records, without it being necessary for a person to travel periodically to read the meter. However, the autonomy of the sensor is only ensured if the feed cell (2) is still alive.
To keep the equipment in working condition, it is therefore appropriate to effectively maintain the sensors (1) and replace them before the feed cell (2) reaches the end of its life. To avoid an absence of recording of the measured physical magnitude (s) during a period that elapses between the end of the life of a cell and the replacement of the sensor, the cell manufacturers tend to oversize the cells and to disregard their probable life, while Operators tend to replace sensors long before the end of life disregarded from the cell. Thus,
the sensors are changed more frequently than necessary, which causes an excess in the cost of operation.
The invention proposes to systematically add to the main data provided by the sensor (1), and directly associated with the main function of this sensor, a secondary information element relative to the ambient temperature, immediately adjacent to the sensor device, in order to estimate more accurately the life of the cell.
In addition, this configuration makes it possible to generate alerts if the predefined temperature thresholds are exceeded, such as temperatures that are too low, that cause a risk of freezing a water meter, or vice versa, temperatures that are too high, causing a risk of damage to the cell or plastic of a sensor device placed for example outside, under the sun, in southern Europe.
The measuring sensor (1) comprises, according to the invention, a temperature measuring means (7) placed in the vicinity of the cell (2). This measurement means (7) may consist of a platinum resistor, or any other known means of measuring the temperature, appropriate for the intended application. The measuring means (7) can be immersed, with the cell (2) and the electronic circuits, in a coating of
maintenance and / or protection, mainly plastic.
The measuring means (7) can be connected to the terminals of the microprocessor (6). A connection is then established between the measuring means (7) and the transmitter (3). The latter, driven by the microprocessor (6), is designed to transmit the measured values of the temperature at determined intervals, in addition to the values of the physical magnitude (s), mainly the volume of liquid delivered, to which the sensor is assigned. . Four measurements of temperature per day can be taken at regular intervals, in which case the transmissions of the measured values of the temperature will take place every six hours.
The receiver (5) is designed to store the temperature values, estimate the life of the cell (2) of the sensor in question, post these measured values, and determine a replacement date for this cell. Accordingly, the receiver (5) comprises a computing unit (8), comprising microprocessor and memory, programmed to perform the operations to store the measured values and to estimate the life of the cell.
The microprocessor (6) of the sensor (1) receives, processes and communicates to the transmitter (3) other information other than the temperature in the vicinity of the cell, mainly the volume consumed in the case of a
fluid gauge, fluid pressure or other physical quantity supplied to the microprocessor on one or more connections such as indicated by (9).
The systematization of the secondary temperature measurement can be done at a marginal cost because a microprocessor often comprises a temperature measuring means for the purpose of compensating for the internal clock offset. In terms of measurement accuracy, a tolerance of ± 1 ° C is fully acceptable, which remains compatible with low-cost solutions, without requiring a particular calibration.
The memory of the computing unit (8) of the receiver (5) can be loaded with the typical temperature profiles for the cell, which correspond to a highly probable life.
Figure 3 illustrates three possible typical profiles, where the temperature is displayed on the Y axis, and the time on the X axis.
The profile (A) corresponds to a long life: this is the case of a cell exposed to a suitable average temperature of the order of 15 ° C, with temperature variations of, for example, between 0 ° C and 30 ° C. The life of the cell is estimated at 20 years.
The standard profile (B) corresponds to a life
average, for example, 15 years. This is the case of a cell exposed to temperatures that vary, for example, between -2 ° C and 40 ° C.
The profile (C) corresponds to a short life. This is the case of a cell exposed to more severe temperature conditions, between -10 ° C and 50 ° C, for example for sensors located in mountainous areas or in areas exposed to the sun.
The counting unit (8) stores the measured values of the temperature, establishes a real profile (E) and compares it with the typical profiles shown in Figure 3, and deduces from this the probable life for the cell. With the illustrated profile (E) narrowing beyond the profile (A) but located inside the profile (B), it should be estimated that the life is that of the profile (B), namely 15 years.
To simplify, only three typical profiles have been shown in Figure 3, although it is clearly possible to refine these typical profiles and take into account the frequency with which the temperature limits of a profile are exceeded by the measured values.
The counting unit (8) is also advantageously designed to activate an alarm when the measured values of the temperature exceed a certain threshold.
For example, in the case of a water meter that can be damaged by frost, when the temperature indicated by the sensor (1) is below, for example, -5 ° C or -10 ° C, the unit computation (8) activates the transmission of an alert, preferably for the operator of the network, in order to have the user notified of the risks of freezing this water meter, so that he can take action in order to verify and / or improve the thermal insulation of this meter.
Similarly, in the case of a high temperature, for example greater than +60 ° C, capable of destroying the cell, an alert is sent by the computing unit (8), usually to the network operator, in order to notify you that the cell is withstanding thermal conditions harmful to its correct operation over time, and that it is appropriate to take measures to correct this overheating.
A first example of a specific application refers to a water company. The invention makes it possible to identify, in a period of very cold, the meters that are subjected to excessively low temperatures that could apparently freeze them and therefore irreparably damage them, which would cause considerable leakage and expensive water damage for both the user and for the water company. On the basis of information from the
temperature charged by the computer unit (8), the water company can initiate preventive actions, for example, warning the users involved to motivate them to correct the problem, installing isolation devices that cover the water meters.
Another example of application would be related to a water company that manages a population of sensors that, in summer, may be subjected to excessively high temperatures, which have a harmful impact on the life of the cells. On this basis, the water company can either take into account this information in order to correct the life expectancy of the sensors subjected to these high temperatures and plan an early replacement, or put on the site a protection against heat.
The invention makes it possible to substantially improve the maintenance of the autonomous measurement sensors. The operating costs of a delivery facility with meters equipped with remote registration sensors are substantially reduced.
